* Outline
  - Showing output to the user.
  - Taking input from the user. 
* Question 1
  What happens when you do ~print "x is %d y is %f" %(x, y)~
* Solution 1
  ~int~ value of ~x~ and ~float~ value of ~y~ are printed corresponding to the
  modifiers used in the ~print~ statement
* Question 2
  Enter the number 5.6 as input and store it in a variable called
  ~c~. 
* Solution 2
  #+begin_src python
    In []: c = raw_input() 
    5.6
    In []: c
  #+end_src
* Question 3
  What happens when you do not enter anything and hit enter
* Solution 3
  #+begin_src python
    In []: c = raw_input() 
    <RET>
    In []: c
  #+end_src
* Question 4
  How do you display a prompt and let the user enter input in a new line
* Solution 4
  #+begin_src python
    In []: ip = raw_input("Please enter a number in the next line\n> ")
  #+end_src
* Summary
  You should now be able to --
   + Print a value "as is" 
   + Print a value using using modifiers
   + Accept input from user
   + Display a prompt before accepting input
* Thank you!
